Sometimes it's both enlightening and entertaining to revisit older articles from the past. In this case, a Reuters article from November 2007 shows how foolishly arrogant both Nokia and Microsoft were after hearing that Google would be entering the mobile market with a new operating system. The executives at both Nokia and Microsoft vastly underestimated the impact that Google could have in the market.

Here we are almost seven years later and Android is the dominant mobile OS on the planet by a large margin. Android devices make up 80% of the world market with a total of 1 Billion activated devices. Now Nokia has fallen so far that Microsoft had to buy them out, and Microsoft is still struggling to get mobile marketshare percentages in the double digits.

Here's what Nokia said back then,

"We don't see this as a threat."
And here is Microsoft's comment,

"It really sounds that they are getting a whole bunch of people together to build a phone and that's something we've been doing for five years. I don't understand the impact that they are going to have."
This seems like perfect proof that you should never underestimate your competition, especially one as capable and powerful as Google. As an interesting sidenote, at that time Apple didn't have any comments about whether they felt Google entering the market would be a threat, but here's what they had to say,

"We have a great relationship with Google and this doesn't change anything. They are certainly an important partner for iPhone."
That didn't turn out the way they thought it would either, did it?
